Sid Meier's Civilization VI is currently free (Epic via Prime)
(luna.amazon.com)
A gaming community free from the hype and oversaturation of current releases, catering to gamers who wait at least 12 months after release to play a game. Whether it's price, waiting for bugs/issues to be patched, DLC to be released, don't meet the system requirements, or just haven't had the time to keep up with the latest releases.
From my experience, the first 50-100 turns are kinda boring (unless you're fighting barbarians) but things get more interesting when you have many cities and things to manage. The game takes a long time to hook me, but when it does it hooks me good. :)
